IMPROVEMENT IN GAS-BULRNERS.

Speciliraiion iormiugpz-u't of Letters PatPntNo. 105,768, dated July 26, 1870.

l'o aZZ whom, it may concernile it known that I, JOHN F. BARMER, of Springfield, in the county of Hampden and State ot' Massachusetts, have inventeda new Improvement in Gas-Burners; and I do hereby declare the following, when taken in connertion with the accompanying drawings and thcletters of reference inarked thereon, to be a Shell through line A l otlFig. 2. Fig. 5 is a Vertical longitudinal'section ot' the burner: through' line C l) ot' Fig. 3. Fig. 6 is a side View of another mmlitieation ot' myinvent-ion.

Fig. 7 is aside View ot' the shell. Fig. 8 isaside View of the burner. Fig. 9 isa vert-ical longitudinal section ot' the shell through line E F of Fig. 7, and Fig. 1() is a vertical Section through line (i II of Fig. S.

` My invention relates' to a device for regulating the iiow of earbureted air or gas from the burner to its p'oint ot' combustion; `and it consistsv of a burner having a screw-thread made upon its` lower part, upon which is itted to turn freely thereon a shell or tube, also having a screw-thread upon its interior-lower part, and the bore ot' Said tube or Shell is 4somewhat larger in diameter than the diameter of the upper part of the burner upon which it turns. i

A series of pel'i'orati ons are made in the lower part of the burner, so that when the burner is made or Set for the combustion of carbureted air or gas of anyvcertain quality the amc may be increased or diminished by turning the shell either up or down, as the case may be, the shell, in its movements up or down, either closing or opening the holes'or perforations and let-ting out or stopping the flowfot'l the gas through the Said holes as it is Amoved up or down.

In the use of carbureted air for illuminating purposes it is almost always the case that when the gasoline is first placed within the generator it gives off a much greater amount of vapor,V and the air; in passing through the generator, absorbs a greater .amount of .the carbon, and consequentlybecomes more thor` oughly charged with and lis much vricher in the illuminating qualit-ies of the gasoline than when the generator has been charged fora greater length of time', and as a result the carbureted air iS sometimes too rich to make a desirable light, with the Sameamount passlng out the burner; and at other times,.as

when the generator has been charged a longer time, the earbureted air iiowing through the burner is deficient in illuminating-power,and the light or flame produced is not uniform in its power or steadincss, and is sometimes liable to produce a smell of smoke when t-oo rich in carbon. Myinnention is designed to obviate all difficulty in this respect, as the burner is set or made to let out at the tip the minivmum quantityot' gas that will produeea good llame, and as the gasoline remains longer in the generatoraml becomes weaker in its illuininating qualities, the outertube or Shell may be turned so as to let out more gas and increase the llame without liability to smoke.

rlhat others skilled in the art may be enabled to make and use myinvention, I will now proceed to describe its construction and mode of operation.

In the drawings, L represents the main part of the burner, which is made similar to the common burner, except that the lower part hasascrcw-thread made upon the outside and inside.

Figs. 1, 2, 3, 4, and 5 represent one modifi! cation, in which L is the burner, having the usual screw-thread made upon the lower interior part, by which to secure it to the pipe. At a is a conical shoulder or seat upon the exterior, (shown in Figs. 3 and 5,) and a screw-thread, d, made upon the exterior otthc lower end, and the Small holes c are made either at the Seat a or just below it. I is a shell or tube, the inside diameter ot its upper part being somewhat greater than the outside diameter of the part L, and upon the interior of the tube, at a, is a conicallyshaped seat, made to fit upon the exterior seat, a, upon the burner L. A. screw-thread, d, is made upon'the interior of the lower part of the tube I, which fits the thread d upon tlie exterior of the burner L.

The operation of this modification is aS follows: When the tube I is turned entirely onto the burner L, the inner Seat, a, tits down upon theshoulder a of the burner L, and the only er by the screw-threads d and d upon the inplace of egress for the gas is'through the slot at the tip. Vhen the gasoline is fresh or new, this slot will b e quite sufiicient to supply the Haine; but as the gasoline becomes more eX- ha'usted of its carbon the tube or shell I may be turned up alittle, so that the seat e' shall be raised slightly from the shoulder a', and more or less ofthe gas will pass out through the holes 'e and pass up between the tube I and the burner L as the tube I is lturned up or down, and when the gas which ,escapes through the holes c and passes up between the tube and burner reaches the top it unites with that passing out the slot at the tip, increasing the volurne and ilaine. In this device the gas, after passing out through the holes c, is prevented from passing down between the tube and burnside of the tube and outside of the burner.

In the modification shown in Figs. 6, 7, 8,

9, and 10 both the burner and regulating-tube are similar to that already described, except that the thread d upon the outside of the burner L is carried up higher, and the holes G are made below the top of the outer thread, but above thetop of theinside thread. rlhethread upon the inside of the tube I- is not so long` as l tle outside thread upon the burner L, but is considerably less, so that when the tube I is turned entirely down on the burner the holes will be above the thread on the inside ot' the L tube, as there is no inside seat in the tube I'to l operate upon a beveled or conical exterior shoulder `uponthe burner L, as in the other l modification. The operation of this modification is as follows: If the flame be too weak, the tube I is turned down upon the burner L until the top l of the inside thread of the tube begins to pass below the holes c, when the gas will escape I and pass up between the tube and burner and increase the Yi'lame, as before. Il it should be desirable to stop the escape of gas through the holes c, it is only necessary to turn up the tube upon the burner, and when the thread inside the tube covers the holes c then there will be no escape of gas.

It will be seen that the principles of the operation of bot-h modifications are very much alike and are intended to accomplish the same object, although the tube turns up in the first case to let out more gas, while it turns down in the second ease, both being equivalent, however, in their operation, and accomplish the saine result.

I am aware that gas-burners have been heretofore made to give an additional supply of gas to the flame; but in those that I have seen they consisted of more pieces and were con'- siderably more expensive to manufacture, and in their operation the vburner ,revolved with the tube this causing the iiaine to revolve also. rlhisis very objectionable, as it is often desirable to have the iiame stand in one particular direction. In this device the flame docs not turn in the least, while the whole burner may consist of only two pieces, and is cheaply made, and its operation and eiicct are perfect.

Having thus described my invention, what I claim as new, aud desire to secure by Letters Iatent, is-

An improved gas-burner consisting of the burner or pillar L, having holes c c therein, and provided with the movable or adjustable shell or tube I, all constructed and operatingI substantially as and for the purpose herein described and specified.
